You're most likely accustomed to the staccato, stop-and-start operation of traditional forced-air cooling and heating. Systems cycle on and off, in the process creating uncomfortable, sometimes drastic indoor temperature swings. To safeguard your comfort, a Mitsubishi Electric system works in a completely different way. Rather than subject the environment to ups and downs, the system constantly monitors a zone's temperature and precisely adjusts to match the demand at any given time. That way, you always get the temperature that you expect.
